HP Matrix Operating Environment 7.2 Logical Server Management User Guide

5. Select the VCEM and the Change Logical Server Associations check boxes and insert the VC
Domain Group name in both fields and click Refresh.
6. Try provisioning again.
Use portable WWNs and MAC addresses for VC Domain Groups
VCEM VC Domain Groups that use hardware default settings for WWNs and MAC addresses
are not supported in logical servers. Logical servers require portable WWNs and MAC addresses
that can be moved from blade to blade. HW-DEFAULT settings used in VC profiles are those of
the physical server blades, and those WWNs and MAC addresses will not move with the profile
on a profile migration.
Suggested action
Select the VCEM-default option for portable WWNs and MAC addresses when you create a VC
Domain Group in Virtual Connect Enterprise Manager. See Virtual Connect Enterprise Manager
documentation for details.
Do not use valid host name as logical server name
When you create or import a logical server, do not give the logical server the same name as a
valid host name in your environment. Although logical server management prevents you from using
the name of an existing system in Systems Insight Manager, if a host with that name is discovered
after you create or import the logical server, the logical server information is overwritten and Matrix
OE visualization no longer displays the logical server.
In addition, host names must be unique in the Matrix environment.
Suggested actions
1. Restart the Logical Server Automation Service. This modifies the Systems Insight Manager
system so that the host named object is once again a logical server.
2. If the logical server is activated, deactivate it using Tools→Logical Servers→Deactivate....
3. Rename the logical server using Modify→Modify Logical Server.... On the Identity tab, change
the name of the logical server to a new, unique name.
4. Delete the Systems Insight Manager node for the original logical server. To delete the node,
click All Servers, select the system with the new name from step 3, and click Delete.
5. Restart the Logical Server Automation Service. This recreates the logical server with the new
name.
6. If the logical server was previously activated, then deactivated, reactivate it using Tools→Logical
Servers→Activate....
7. Use the Systems Insight Manager Option→Discovery... menu selection to rediscover the host.
Oversubscribing the number of networks
It is possible to "over subscribe" the number of networks for a Virtual Connect logical server. If the
logical server requires more network connections than are supported by the NICs on a given blade,
some of the networks specified in the logical server will not be available to the operating system.
Insufficient NICs error when activating or moving logical servers (Virtual
Connect Flex-10 support)
Virtual Connect Flex-10 Ethernet Module for c-Class BladeSystem is supported in this release.
Flex-10 technology increases the number of NICs per connection. If you activate or move a Virtual
Connect logical server and you have a large number of networks configured, the blades with
Flex-10 are shown in the list of available targets with a soft error icon indicating insufficient NICs.
